Take him to the vet and they should be able to confirm and get him the treatment he needs. As well as works he could have bloody diarrhea that just looks like blood/water. That is easy to treat by the vet with meds but is serious as he could get really dehydrated very quickly.

Take your cat to the vet whenever there is something unusual going on--you know better than anyone if your cat is not acting "normal." Bloody feces should not be ignored. Get a vet check. But, in my own case, I have "cured" Harvey's soft stools by giving him fiber rich hairball control food--when I should have taken him to a specialist to check for IBD etc. But I have been told by my local vet (who is very good) that bloody stools are often caused by things as simple as the cat having ingested something like human hair, which can cause intestinal bleeding. Please take your cat to the vet, remembering that bloody feces may or may not be a symptom of a major medical problem. We (well, me at least) are not medical experts here, but we are always available for support. Keep us posted. But do go to the vet.
